ResumePartialDownload property

True to resume a previous partial download, false to discard a previous partial download. The default is false.

Only at most one synchronization command (ULSyncParms.DownloadOnly, ULSyncParms.PingOnly, ULSyncParms.ResumePartialDownload,
or ULSyncParms.UploadOnly) can be specified at a time. If more than one of these parameters is set to true, a ULSQLCode.SQLE_SYNC_INFO_INVALID
SQLException is thrown by ULConnection.Synchronize().
